Google I/O 2026 started at the Shoreline Amphitheatre in California, and the Google stock price target picture going into today already looked about as bullish as it has in years. Alphabet shares hit a fresh all-time high on Monday, up roughly 140% over the past year, and right now 63 analysts tracked by S&P Global carry a consensus Strong Buy on the stock, with an average Google stock price target of $427.89. The range runs from $334.22 on the low end to $515 at the top, and that spread tells you there is still real disagreement on Wall Street about how fast Alphabet’s AI revenue actually scales from here.

A wave of price target hikes hit the tape. Loop Capital moved its call to $490 from $355, keeping a Buy. Oppenheimer also kept its Outperform and lifted its number to $445 from $425. Arete Research moved to $425 from $405. Bank of America’s Justin Post reiterated a Buy with a $430 target heading in, noting that the Google I/O announcements around AI subscriptions and agent capabilities could also strengthen investor confidence further. Citi sits at $447, also maintaining a Buy.

The most aggressive recent move came from Mizuho’s Lloyd Walmsley, who pushed his Alphabet price target to $460 and tied it directly to his view on Google Cloud’s growth trajectory. Walmsley stated:

“We believe consensus estimates continue to significantly under-model Google Cloud revenue and operating income potential over the next two years.”

His model now calls for 70% Google Cloud revenue growth in 2026 and 59% in 2027, well ahead of Street consensus of 58% and 47% respectively. He also wrote that Alphabet has shifted “from AI Loser to AI Winner and deserves a premium” and set his price target at 30x his 2027 GAAP EPS estimate, above the company’s three-year historical range. At the time of writing, 57 Buy ratings, six Hold, and zero Sell calls sit on record across 63 analysts. That kind of alignment is not something you see very often on a $4.8 trillion company.

What Gemini 4 Means for the Alphabet Stock Price Target

One of the first things investors want to hear about this morning is whether Google actually unveils Gemini 4 today or sticks with a 3.5 update. Citi noted that based on Google’s roughly three-to-four month launch cadence since Gemini 3.1 Pro in February, a full generational leap is possible but not the obvious base case. Mizuho also wrote that a Gemini 4 debut would push Google “back up to the bleeding edge of the frontier,” and most of the Street agrees that it matters for the Google stock analyst ratings picture, even if Cloud numbers also carry a lot of the narrative right now.

Lo Toney, founding managing partner of Plexo Capital and also an early Alphabet backer via Anthropic, had this to say about why the full-stack story gives Google a structural edge over rivals at this year’s Google I/O conference:

“Google is probably the best-positioned company to monetize AI at scale because it controls almost every layer of the stack. We’ve never really seen a company that has that complete vertical integration from top to bottom to be able to support AI.”

Google Cloud posted $20 billion in Q1 revenue, up 63% year-over-year, faster than Azure at around 30% and AWS at 28%. The backlog came in at $462 billion, nearly doubling quarter-over-quarter, and gen AI product revenue grew roughly 800% year-over-year. Those are the numbers that keep moving the Google stock price target upward across desks, and also the reason so many of the Alphabet stock I/O 2026 previews coming out of research teams this week read more like victory laps than cautious previews.

Toney also called TPUs one of the most underappreciated parts of the Alphabet thesis, and Gene Munster, managing partner at Deepwater Asset Management, put the chip opportunity in context. Munster stated:

“There is a benefit to owning the full stack in terms of the speed that you can innovate. When you’re building on your own custom silicon, for example, that’s an advantage of speed. When you have access to power, you can get data centers up more quickly. That’s a speed advantage, which is important.”

TPU Sales and What Still Needs to Get Answered Today

Google disclosed in Q1 that it starts delivering custom TPU chips to outside customers in the second half of 2026, with broader expansion coming in 2027. Right now, most of the Google stock analyst ratings on the Street do not fully model that revenue stream yet, which is part of why the more aggressive calls land as high as $490 and $515. Munster estimates the broader AI chip market runs at roughly $500 billion annually, so even a modest share of that market moves the needle for Alphabet in a real way.

What Wall Street also wants to hear about today, specifically around the Google I/O announcements in the next few hours, is how Google plans to monetize AI Mode in Search. Mizuho flagged that 93% of AI Mode searches right now end without an external click, and organic click-through rates on AI Overview queries are down about 15%. That is the tension at the core of the Google stock price target debate heading into today: Google Cloud and TPUs push the bull case higher, and the question of ad monetization in AI Search keeps the bears from fully giving up. The Google I/O 2026 keynote that started this morning is the first real chance to start answering that question in public.
